Appleton EFD/EFDB and EDS Series Explosionproof Control Station, Malleable Iron

Appleton EFD/EFDB and EDS Series factory sealed control stations are explosionproof, dust-ignitionproof enclosures that confine device arcing within the housing, preventing ignition of surrounding atmospheres during control operation. Built with malleable iron bodies and covers, this family offers push buttons, selector switches, and pilot lights for remote or local control and status indication of motors and other equipment used with contactors or magnetic starters. Rated Class I, Division 1 and 2, Groups B, C, D; Class II, Division 1 and 2, Groups E, F, G; Class III; and NEMA 3, 7CD, 9EFG, these stations are designed for classified areas where flammable vapors, gases, or combustible dusts are present.

Key Features

  • Explosionproof, Dust-Ignitionproof Construction: Confines arcing within the enclosure, ideal for chemical and petrochemical plants, refineries, and other process industries.
  • Durable Construction: EFDB control stations use a malleable iron body with copperfree (4/10 of 1% max.) aluminum cover; EDS units use a malleable iron body and cover, each with a triple-coat finish of zinc electroplate, chromate, and epoxy powder coat.
  • Factory Sealed: Pigtail leads from push buttons are factory sealed in a sealing well, eliminating the need to add sealing fittings and compound at each conduit entrance.
  • Heavy-Duty Push Buttons: Rated 10 Amp, 600 Vac, with silver cadmium oxide contacts sealed in a corrosion-isolated lower phenolic chamber for positive, long-term contact.
  • Pilot Lights: EFD/EFDB factory sealed pilot lights include a red jewel/guard assembly and 120 Vac/Vdc, 50/60 Hz, 6 Watt, Type 6S6 lamp for visual confirmation of remote or local electrical function.
  • Stainless Steel Hardware: Stainless steel push button shaft operates within a stainless steel bushing, and corrosion resistant captive stainless steel hex head cap screws secure covers to the body.
  • Lockout Capable: EFD/EFDB momentary push buttons include lockout type guards as standard, with a hole accepting locks up to 1/4" hasp to prevent unauthorized operation.
  • Selector Switches: EFD/EFDB factory sealed selector switches use nylon cam-operated construction for 2-position or 3-position maintained contact operation with high thermal and arc resistance.

Why Appleton?

Appleton EFD/EFDB and EDS control stations combine malleable iron construction, triple-coat corrosion protection, and factory-sealed wiring to deliver dependable, code-compliant performance in demanding classified environments. Sealed silver cadmium oxide contacts, stainless steel hardware, and lockout-ready push buttons help ensure long, trouble-free operation for professional electrical installations.

What this is: EDS175-RU1 is a complete, factory-sealed, dead-end 1-gang control station built with a malleable iron body and a 3/4" hub, furnished with a rocker-arm handle rated 10A at up to 600 VAC. The rocker arm can be padlocked in either the ON or OFF position. This is a working device (not a blank cover or an empty body) — ready to wire and install. It differs from the EFD275-NL-Q listing (a 2-gang body without the switch installed) and from ESKBBQ (a blank cover with no device at all).

Appleton EDS175-RU1 – Frequently Asked Questions

1) Is the Appleton EDS175-RU1 a complete control station or just an empty enclosure?
EDS175-RU1 ships complete and ready to wire. It's a factory-sealed, dead-end 1-gang control station with a malleable iron body, a 3/4 inch hub, and a rocker-arm handle already installed. Not a blank cover, not an empty body. If you need a 2-gang body without the switch fitted, that's the EFD275-NL-Q; a blank cover with no device is ESKBBQ.
2) What hazardous location classifications does the Appleton EDS control station carry?
Rated for Class I, Division 1 and 2, Groups B, C, D; Class II, Division 1 and 2, Groups E, F, G; and Class III. Enclosure ratings are NEMA 3, 7CD, and 9EFG. That covers flammable gas and vapor atmospheres including hydrogen (Group B) plus combustible dust and fiber areas, which is why these go into refineries, chemical plants, and grain or process handling.
3) Do I need to install seal fittings at the conduit entries on this Appleton control station?
No separate seals are needed at the station itself. The pigtail leads from the push buttons are factory sealed in a sealing well, so you don't add sealing fittings and compound at each conduit entrance. That saves the labor and the compound cure time on every unit. Seals elsewhere in the run are still governed by your installation code.
4) Can the EDS175-RU1 rocker handle be locked out for maintenance?
Yes, the rocker arm padlocks in either the ON or the OFF position, so you can secure a circuit energized or de-energized. On the EFD/EFDB momentary push buttons the lockout guard is standard and the hole accepts locks up to a 1/4 inch hasp.
5) What conduit size does the Appleton EDS175-RU1 control station take, and can it be fed through?
It has a single 3/4 inch hub and it is a dead-end station, meaning one entry only, no through-feed. Plan the conduit run to terminate at the box rather than passing through it.
6) What are the contact ratings on the Appleton EFD/EFDB and EDS push buttons?
10 amps at 600 VAC. Contacts are silver cadmium oxide, sealed in a corrosion-isolated lower phenolic chamber. That rating suits pilot-duty control circuits for contactors and magnetic starters rather than switching motor load directly.
7) Will a malleable iron explosionproof control station hold up in a corrosive refinery or coastal plant?
The EDS bodies and covers are malleable iron with a triple-coat finish: zinc electroplate, then chromate, then epoxy powder coat. The push button shaft is stainless steel running in a stainless bushing, and the covers are held by captive stainless steel hex head cap screws. On the EFDB variant the body is malleable iron with a copperfree aluminum cover (4/10 of 1% max copper), which is the usual choice where acetylene-bearing or copper-sensitive atmospheres are a concern.
8) Should I order a push button, a selector switch, or a pilot light for my motor control point?
Depends what the point does. Momentary push buttons are for start/stop commands to a contactor or magnetic starter and come with lockout guards. Selector switches use nylon cam-operated construction and give 2-position or 3-position maintained contact, so use them for hand/off/auto or local/remote modes that must stay put. Pilot lights on the EFD/EFDB are indication only, supplied with a red jewel and guard assembly and a 120 Vac/Vdc, 50/60 Hz, 6 watt Type 6S6 lamp. The EDS175-RU1 specifically is a rocker-arm maintained device rather than a momentary button.
